To all whom t may concern:

reliable in operation whereby the escape of tridge storing space.

more than one cartridge at a time from the cartridge storing means tothe cartridge conveying mechanism is prevented' and undesirableinterferencel with the proper' fimctioning of said mechanism therebyavoided. y y

Another object is the provision of mechanism wherein a cartridge stop iscontrolled by av member which serves as both an action bar and acartridge transfer member. Still another object is .to provide amechanism l wherein a cartridge stop is controlled by a member whichserves as an action bar and also contributes to the determining of acar- Other objects of my invention reside in certain arran'gements andcombinations of parts which will become lapparent as the description ofmy invention is hereinafter developed, and will be pointed out in theclaims hereunto appended.

Referring to `the'drawings wherein I have shown what I now consider tobe the preferred form of my invention:

Fig. 1 is a-fragmentary side elevation partly in section, showing myinvention in 'connection withA one type of firearm to which it may beapplied, the action bar and breech block being shown forward and thehammer cocked. g

Fig. 2 is a view similar to Fig. 1 but showing the action tracted.

Fi'g. 3 is a vertical sectional view taken on line 3-3 of Fig. 1 lookingin the direction of the arrows. f

Fig.`4 is a vertical sectional view similar to Fig. 3, except that thecartridge stop bar and breech block re-A and action 'bar'are shownindifferent positions4 than in Fig. 3.

`Fig 5 is a fragmentary horizontal sectional view taken on line 5-5 ofFig. 3.

Fig. 6 is a view in side elevation of the rear portion lof the actionbar.

Fig. 7 is a fragmentary plan view showing art of the action bar.

e firearm in connection with which my invention is illustrated is inmany respects similar to the 'firearm disclosed in my Patent No.908,883, granted Jan.4 5, 1909, and, like the firearm disclosed in saidpatent, includes a barrel 1 secured to the barrel ortion 2 of a frame orreceiver, 4a butt stoc 4 being secured to the stock portion 3 of saidreceiver. T'he parts 2 and 3 of the frame or receiver enclose a chamber`in which are located mostIv of the working `parts 4of the gun,includin'g the breech block 5, cartridge carrier, and hammer 7. Thebreech block 5 ris'reciprocable in the receiver' and at its upperforward end is provided with an upwardlyextending shoulder 8 forengaging the recoil .shoulder 9 in the forward top portion of thereceiver. The carrier 6 1s ivotally mounted on a sleeve 10 mounted 1nthe receiver portion 3, thru which sleeve passes a screw 11 for securingtogether the parts 2 and 3 of the receiver. The hammer 7 is likewisemounted on said sleeve. 10 and is adapted to be driven to firing ositionby a spring 12 which acts upon the ead of a rod or plunger 13 connectedto said .ham-

mer. A trigger 14 is pivoted at 150 in the stock portion 3 of thereceiver andvi's springurged to a position for holding the hammercocked. The parts -above described beingI similar to the correspondingparts disclosed in my prior Patent No. 908,883, above re- A ferred to,nov detailed description thereof is necessary A stationary magazine tube15 is shown beneath the barrel, said magazine tube being mounted at itsrear end in the receiver m0,.

v bined action bar and cartridge ytransfer- 15. The forearm, sleeve, andaction bar may be secured together by a screw 23. As in my abovereferred to Patent No.` 908,883, the rear portion of the action bai isprovided with a shoulder 24 and an inclined face 25 adapted to co-ocrate with a downwardly extendin incline projection 26 from the breech book 5, whereby the breech block4 may be moved into and out ot' itsclosed or breeched-up position (Fig. 1) by movement of the action bar,as fully described in said patent ,Like the action bar shown in mypatent above-referred to, the action bar disclosed herein is provided inits rear prrtion with shoulders 30 and with guideways 27 (Fig. 7) forthe rim of a cartridge and is suitably slotted as shown at 28to'accommodate the carrier'. Any suitable means, such as a spring catch29 shown mounted on the rear part of the action bar and projecting thruthe wall thereof, may be employed for gripping the -rim of a cartridgeabutting against the shoulders 30. As sl1;wn in Fig.

1, when the action bar is in its iorward orI home position the rearmostcartridge in the magazine 15 abuts against the shoulders-30 and the rimof the said cartridge is at the same time gripped by the catch 29. Whenthe action bar is then drawn rearwardly the cartridge aforesaid iscarried rearwardly.

.with 4the action bar, into the position shown in Fig. 2, wherein saidcartridge overlies the carrier 6. Upon then moving the action barforwardly the carrier is raised bythe co-action of a dog' 31, carried bythe action han with an inclined slot in the car-- rier, whereby thecartridge is raised by saidv carrier into engagement with guideways onthe face of the breech block so that the 'latter in moving tobreeched-up" or closed position'will insert the cartridge into thebarrel. The co-actio'i of the carrier dog 31 with the cartridge carrier6 is similar to that disclosed in my patent abovereferred to, said dogbeing carried by a leaf spring 33 attached to the action bar andbeingcammed laterally by the .inclined 50. bottom of a cut 34 in the carrierduring the initial portion of the rearward Inovement of the action barwhereby said dog rides along the side of the carrier during furtherrearward movement of said action bar until at the end ofsaidrearvrardmvement said dog snaps-into the slot 32.

inasmuch as the action bar, in addition to operating the breech blockand cartridge carrier, also carries cartridges from the magazine tube tosaid carrier, said action bar may be appropriately termed a commember.

It should also be noted that the action bar co-operates with themagazine tube to define a cartridge storage space, the rear is inforward or home position, as shown in Fig. 1. Thus both the action barand the magazine contribute to the determining of the space for storingcartlidgcs that are to be fed to the cartridge carrier.

ln order to regulate the passage of cartridges from the magazine 15 .lprovide a cartrid e stop or cut-od 35 which is shown pivotally mountedat 35 in the receiver and is provided at its upper end with a bevelednose 36 adapted to project into the path of cartridges in the magazine.Said cartridge stop is also rovided with a toe 3? at its lower end, wich toe is adapted to co-act with a roove 38 in the adjacent side of theaction ar. When the action bar is in forward or home position as shownin Fig. 1 the groove 38 is opposite the toe 37 of the cartridge stop sothat thc latter may y be moved out of cartridge stopping position and acartridge in Contact with the nose 37 at such time will, under theiniuence of the spring-pressed follower 17, rock said stop out ofstopping position (see Fig. 3) and pass rearwardly until said cartridgeabuts the shoulders '30 of the action bar. The groove 38 is'providedwith a beveled or inclined portion 38 so that when ,the action bar ismoved rearwardly said inclined portion 38 cams the toe 37 outwardly andforces the nose 36 into the path of the cartridge immediately precedingthe rearmost cartridge. isl rearward movement of the action barcontinues the side of the latter comes opposite the toe 37 so that whenthe cartridge immediately preceding the rearmost cartridge strikes nose36 the cartridge stop cannot be'rocked and further rearward movef mentof all cartridges forward ofthe rearmost cartridge isV prevented. Thusmovement of more than one cartridge at a time' from the lmagazine isprevented and objectionable interference with the operation of themechanisnrfor conveying cartrid es from the magazine to the barre: istheriy avoided.

For limiting the movement of the action lbar various means may beemployed., I have, for purposes of illustration, sh'own a projection 39,which, in co-operation with closed maybe modified and varied innu lacmerous ways without departing from the spirit of my invention.

Having described my invention what I claim and desire to secure byLetters Patent 1s:

1.
